OK, you got me. I have read bottles of "baby powder" which is corn starch, several brands, and in the house. I do not have actual "talcum powder" in the house, but I do see it is available.
I have used kitchen corn starch with very good results. I have also read horror stories of the perfumes interacting with paint. I have never encountered those problems using corn starch. I never used baby powder to find out if it would be a problem with the paint.
